Specification of Letters Patent.

Patented July 10, 1906.

Application filed May 22,1905. Serial No. 2611.704.

To all whom it may concern:

Be it known that I, PHILIP S. 0LT, a citizen of the United States, residing at Pekin, in the county of Tazewell and State of Illinois, have invented certain new and useful Improvements in Duck-Calls; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention pertains to improvements in duck-calls, and has for its object to provide an adjustment for the reed whereby tones of varying pitch may be had.

e invention relates also to certain details of construction to be pointed out in the following specification and in the accompanying claims.

. In the appended drawings, which form a part of this application, Figure 1 is a longitudinal section of my improved duck-call. Fi 2 is a top view of the portion thereof whidli. contains the reed. Fi 3 is a view of the small end of the mem er shown in Fig. 2. Fig. 4 is an end view of an outer tube shown in Fig. -1, showing a metal bushing therein. Fig. 5 is a view of the member shown in Fig. 2 as viewed from the large end. Fig. 6 is a perspective view of a portion of the member shown in Fig. 2.

In the figures, A indicates an outer tube member having a short ta er at one end in its bore,within whichis seate a correspondinglythe said tube bein constructed, preferably, of hard rubber, a

sired, as will be understood.

At 0 is a tapered member having a bore D opening outward at its large'end, as shown. Substantially one-half of the said member is removed by cutting it longitudinally and then transversely. This removal exposes the bore D, as shown in Fig. 1, said bore thus being changed into a roove, as at E. At F is a reed, preferably of ard rubber, whichentirely covers the said groove E, its rear end bein held by suitable means within the member In the drawin s this is accomplished by providin a slit in t e member 0, as at G, into which t e reed is slipped. A notch at 0 above the reed receives a transverse strip G, as shown in Fig. 1. tion is common to many forms of duck-calls and I attach no particular claim thereto. I now provide the said member 0 with a longitudinal groove H, which follows the taper of may be used, if defectly we However, this construc said member and receives a strip of metal J L may be placed at any desired point on the reed within the limits of movement of said strip. The latter is provided with a fingerpiece at O betweent 1e staples M and N and serves both for shifting the strip and for lim- I iting its movements between said staples.

It will be noted that although the bore D of the member C is exposed by removin the upper forward half of the latter the said ore is closed by means of the reed and the strip G, so that air-pressure through the outer tube A must pass beneath the reed at its forward end, said forward end being turned up sli air.

n operation, as in other calls of this kind, the reed. is'made to vibrate by forcing air thereunder by blowing with the mouth into ghtly to admit the the open end of said tube A. Now when the foot of the strip J is positioned at the root of the reed the latter will emit a deep tone. If,

however, the strip J is shifted to carry its said foot to the dotted-lineposition in Fi s. l and 2 the tone will be much higher. t is evident also that various other tones will result by positionin the foot between these limits. When the .calIis being used on a very windy day, the tone is preferably a low one, since it will carry farther, while in a more quiet day the hi her tones are used, the person using the 051 varying the notes to suit his wishes and knowledge as to the particular require ments. Q

In brin ing out my improved call I am perployed heretofore for varying the tone of the reed; but I am not aware of a device employing the means used by me for accomplishing this purpose.

Since the strip J slides on the tapered member Owhile its foot moves at a different angle, it will be seen that considerable pressure is maintained on the reed, that pressure increasin as the foot approaches nearer the free end of said reed, thus insuring a firm tone vIOO aware that means have been emrather than a buzz or rattle, as will be understood.

I may vary the construction and arran e- I ment of my improved duck-call without eparting from the spirit and intent of them-- tacting at its lowermost end with the reed,

the said member adapted when shifted toward the free end to contact with greater pressure upon the said free end than at the root thereof, due to its inclined position.

2. In a duck-call, a reed-carrying member, a reed held therein parallel with its axis and a member lying in an inclined plane and shiftable in that plane and having its lowermost end slidin in contact with the reed whereby when shi ted down such inclined plane its contact end bears with increasing pressure toward the free end thereof as described,

guides in which the adjustable member is carried, a finger-piece adapted to shift be tween the guides, the latter for limiting the member in its movements, and a body portion in which the reed-carrying member is removably inserted substantially as shown.

In testimony whereof I afiix my signature in presence of two witnesses.
